I agree in thinking that there is such a class, I replied.

Is there not also a second class of goods, such as knowledge, sight, health, which are desirable not only in themselves, but also for their results?

Certainly, I said.

And would you not recognize a third class, such as gymnastic, and the care of the sick, and the physician’s art; also the various ways of money-making — these do us good but we regard them as disagreeable; and no one would choose them for their own sakes, but only for the sake of some reward or result which flows from them?

There is, I said, this third class also. But why do you ask?

Because I want to know in which of the three classes you would place justice?
